If you tried using System Restore to fix a problem but the problem remained or other problems were introduced, you can undo the restore operation. After you undo System Restore, you can try using a different restore point.

My thought is to take the 'puter back to factory defaults. I have the discs and have been told I simply reinstall using these discs. This is a last ditch effort to avoid having to purchase a new machine.

Tried going into system maintenance to use Restore option. I don't see where I can get it to go back to factory defaults. It just wants to take me back to several update dates, these falling in this calendar month. Tried setting a restore point bt typing in Factory Defaults, but that didn't work. Any suggestions?

13 Click on "Recover to out-of-box state," then click on "Next."

14 Click on "Next" to begin the restoration process.

15 Allow the Toshiba recovery program to work. This may take several minutes.

16 Press any key on the keyboard when prompted to do so to restart your restored Toshiba Satellite A135 laptop.

Now a couple more questions. Years back I had installed AVG Anti Virus, Super Anti Spyware and Malware bytes. Are they still the main recommended protection for the computer? Are the free editions still adequate for a casual surfer of the net? McAfee seems to be already installed, but I know I used AVG.

McAfee's a trial version that came pre installed, I would consider a free version for casual user like AVG, Avast or Microsoft Security Essentials anyone of them is ok. SuperAntiSpyware and Malwarebytes are both good ideas to have too.

You should first remove the McAfee anti-virus before installing another AV program. Don't be surprised to see more updates than the 79 you have already gotten. Remember, this restore took the computer back to the date it came out of the box, so any updates since that time will have to be installed again. Also, any programs or applications that you installed since it was new will need to be installed again if you want them.

If you haven't used the McAfee consumer product removal tool, that would be a good idea to make sure all residual files are removed that could cause conflict. Be careful when downloading to prevent from installing any foistware that is offered with the download. See link below:
